The Chris King Ceramic Bearing Bottom Bracket is identical in construction and compatibility to the stainless steel bearing bottom bracket. All the Chris King qualities you love remain the same - Durability, Serviceability and Performance.

To this Chris King have added ceramic balls, which are lighter, harder and with greater roundness than stainless balls, for a bearing with exceptional speed and strength.

A bottom-bracket specific upgrade to the legendary sealing system allows the bearings to be purged and re-greased using Chris King's precision made injector tool. This combination of strength and serviceability gives them the confidence to offer an industry-leading 5-year warranty on all bottom brackets.

The Chris King bottom bracket is specifically designed for crank systems with outboard bearing cups and is available in the full assortment of colours that only Chris King can do.

Chris King strongly recommends using the BB External Cup Tool and torque wrench for proper installation

Chris King, founder of King Cycle Group, got his machining experience working in the precise and demanding world of medical equipment manufacturing. He designed the original Chris King Headset in 1976 in his spare time and was immediately faced with staggering local and regional demand. In 1977, Chris started King Manufacturing, a contract machine shop jobbing to the medical, microwave, cryogenic, and aerospace industries.

Headset production continued during these years, seeding the regional and national market and developing a strong yet quiet reputation as one of the most exclusive and elite bicycle components available. However, due to the time requirements of other contracted jobs, headset sales never represented more than 10% of the business. In 1987 Chris sold King Manufacturing to Medical Concepts Inc. and founded King Cycle Group, which focused initially on ramping up production of the Chris King Headset to satisfy the demand which was significantly outstripping supply.

Through the years, the strong but quiet reputation grew into a 'cult' following of road racing cyclists across the country. In 1993 King Cycle Group turned their efforts to developing new products, including their hubs and bottom brackets which have in turn become legendary for their quality and performance, and highly sought after by both road and mountain bike riders alike.
